Yes, it sounds distressingly like the Paris Hilton fiasco "Repo! The Genetic Opera," but the trailer and website for "Repo Men" look pretty good.
The trailer is a couple of weeks old, but a new site launched yesterday features a fake ad for The Union, the fine folks who will sell you a Jarvik Heart for the low, low price of $975,000. But the small print at the bottom of the page warns you that "Action will be taken after the sixth day of the fourth month of non-payment. Repo Men will retrieve the property at your expense."
The original site has the "red band" trailer, if you're into that kind of thing.
This is basically the exact plot of "Repo! The Genetic Opera," the musical which came out in 2008 -- but with a markedly better cast. The new film (from our good friends at Universal) star Jude Law and Forest Whitaker as a couple of guys in the not-too-distant future whose job it is to repossess synthetic organs from people who fall behind on their payments.
